STABILITY. 

Make sure the miter saw is placed on  a secure supporting surface and does not slip or move 

during use. If the mobility kit is installed, raise the moveable caster(s) so saw is in its stationary position.

 • 

FOLLOW ALL WIRING CODES 

and recommended electrical connections to prevent shock or electrocution. 

Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit breaker.”

 • 

MAKE CERTAIN

 the blade rotates in the correct direction. The teeth on the blade should point in the direction 

of rotation as marked on the saw.

 • 

TIGHTEN ALL CLAMP HANDLES

, knobs and levers  prior to operation. Loose clamps can cause parts or the 

workpiece to be thrown at high speeds.

 • 

BE SURE 

all blade and blade clamps are clean, recessed sides of blade clamps are against blade and arbor 

screw is tightened securely. Loose or improper blade clamping may result in damage to the saw and possible 

personal injury.

 • 

ALWAYS USE A SHARP BLADE. 

Check the blade to see if it runs true and is free from vibration.  A dull  or a 

vibrating blade can cause damage to the machine and/or serious injury.

 • 

DO NOT OPERATE ON  ANYTHING OTHER THAN THE DESIGNATED VOLTAGE 

for the saw. Overheating, 

damage to the tool and personal injury may occur.

  •

  DO NOT WEDGE ANYTHING AGAINST THE FAN 

to hold the motor shaft. Damage to tool and possible 

personal injury may occur.

 • 

DO NOT

 force cutting action. Stalling or partial stalling of motor can cause damage. To the machine or blade 

and/or serious injury.

  •  ALLOW THE MOTOR TO COME TO FULL SPEED

 prior to starting cut. Starting the cut too soon may cause 

damage to the machine or blade and/or serious injury.

  •

  NEVER CUT FERROUS METALS 

(Those with any iron or steel content) or masonry. Either of these can cause 

the carbide tips to fly off the blade at high speeds causing serious injury.

 • 

DO NOT USE ABRASIVE WHEELS.

 The excessive heat and abrasive particles generated by them may 

damage the saw and cause personal injury.

 • 

NEVER 

have any part of your body in line with the path of the saw blade. Personal injury will occur.

 • 

NEVER 

apply blade lubricant to a running blade. Applying lubricant could cause your hand to move into the 

blade resulting in serious injury.

 • 

DO NOT

 place either hand in the blade area when the saw is connected to the power source. Inadvertent 

blade activation may result in serious injury. 

 • 

DO NOT PERFORM FREE-HAND OPERATIONS 

(workpiece not supported by table and fence). Hold the work 

firmly against the fence and table. Free-hand operations on a miter saw could cause the workpiece to be 

thrown at high speeds, causing serious injury. 

 • 

NEVER REACH AROUND

 or behind the saw blade. A blade can cause serious injury.

 • 

DO NOT 

reach underneath the saw unless it is unplugged and turned off. Contact with saw blade may cause 

personal injury.

 • 

SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. 

Vibration can possibly cause the machine to 

slide, walk, or tip over, causing serious injury.

 • 

USE ONLY CROSSCUT SAW BLADES 

recommended for miter saws. For best results, use only zero-degree 

or negative hook angles when using carbide-tipped blades. Do not use blades with deep gullets. These can 

deflect and contact the guard, and can cause damage to the machine and/or serious injury.

 • 

USE ONLY BLADES OF THE CORRECT SIZE AND TYPE

 specified for this tool to prevent damage to the 

machine and/or serious injury.

  •

  INSPECT BLADE FOR CRACKS 

or other damage prior to operation. A cracked or damaged blade can come 

apart and pieces can be thrown at high speeds, causing serious injury. Replace cracked or damaged blades 

immediately.

 • 

CLEAN THE BLADE AND BLADE CLAMPS 

prior to operation. Cleaning the blade and blade clamps allows 

you to check for any damage to the blade or blade clamps. A cracked or damaged blade or blade clamp can 

come apart and pieces can be thrown at high speeds, causing serious injury.

 • 

DO NOT 

use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic guard. The 

polycarbonate material used in the guard is subject to attack by certain chemicals. 

 • 

ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED.

 Small chip accumulation 

under the saw may interfere with the saw blade or may cause instability of workpiece when cutting.

 • 

USE ONLY BLADE CLAMPS

 specified for this tool to prevent damage to the machine and/or serious injury.

 • 

CLEAN THE MOTOR  AIR SLOTS

 of chips and sawdust. Clogged motor air slots can cause the machine to 

overheat, damaging the machine and possibly causing a short which could cause serious injury.

 • 

KEEP ARMS, HANDS, AND FINGERS

 away from the blade to prevent severe cuts. Clamp all workpieces that 

would cause your hand to be within 6" of the saw blade.

 • 

NEVER LOCK THE SWITCH IN THE “ON” 

position. Severe personal injury may result.

 • 

TURN OFF THE MACHINE 

and allow the blade to come to a complete stop before raising the arm and prior to 

cleaning the blade area, removing debris in the path of the blade, before servicing or adjusting tool. A moving 

blade can cause serious injury.

 • 

PROPERLY SUPPORT LONG OR WIDE WORKPIECES

. Loss of control of the workpiece can cause injury.

 • 

NEVER 

cross arms in front of blade while using tool. Always make a dry run (unpowered) before making a 

finish cut so that you can check the path of the blade or severe personal injury may result.

 • 

ADDITIONAL INFORMATION 

regarding the safe and proper operation of power tools (i.e. a safety video) 

is available from the Power Tool Institute, 1300 Sumner Avenue, Cleveland, OH 44115-2851 (www.

powertoolinstitute.com). Information is also available from the National Safety Council, 1121 Spring Lake 

Drive, Itasca, IL 60143-3201. Please refer to the American National Standards Institute ANSI 01.1 Safety 

Requirements for Woodworking Machines and the U.S. Department of Labor OSHA 1910.213 Regulations.

CAUTION:

 

Do not connect unit to electrical power source until complete instructions are read and understood.

WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during 

use

. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

WARNING: 

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE 

FENCE.

WARNING: 

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities 

contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these 

chemicals are:

•  lead from lead-based paints,
•  crystalline silica from bricks and cement and other masonry products, and 
•  arsenic and chromium from chemically-treated timber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure 

to these chemicals:  work in a well ventilated area, and work with approved safety equipment, such as those dust 

masks that are specially designed to filter out microscopic particles.

  •  Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction 

activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get 

into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING: 

Use of this tool can generate and/or disburse dust, which may cause serious and permanent 

respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust 

exposure. Direct particles away from face and body.
For your convenience and safety, the following warning labels are on your miter saw.
